COMPOUND TOOL.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed January 9, 1917. 2 Serial No. 141,384.

T 0 all whom it may concern:

Be it known that I, WILLIE H. CRUM- MEY, a citizen of the United States,residing at Baxley, in the county of Appling and State of Georgia, haveinvented certain new and useful Improvements in Compound Tools; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to new and useful improvements in compound toolsand the principal object of the invention is to provide a combinationwatch makers tool adapted for various uses and so constructed as to takethe place of several of the ordinary tools now in use so that the userwill have a number of tools at his command without having to lay downone and pick up another tool thus causing considerable loss of time.

A further object of the invention is to provide a device which isadapted to be used as a truing caliper and also to provide a device foruse as a glass cutter for cutting circles and similar figures.

Still another object of the invention is to provide a punch for removingthe jewels of the balance wheel which is arranged to avoid danger ofbreaking the jewel.

With these and other objects in view the invention consists in the novelcombination and arrangement of parts which will be fully set forth inthe following, specification and accompanying drawings, in which Figure1 is a side view in elevation of a watch makers tool constructed inaccordance with this invention.

Fig. 2 is a view from the opposite side of Fig. 1 showing portions ofthe device in section to more clearly illustrate the details ofconstruction.

Fig. 3 is an edge view of the device,

Fig. 4 is a longitudinal sectional view on line 44 of Fig. 2, and

Fig. 5 is a detail View showing pointer and mounting for the same.

Referring to the drawings, 1 designates one of the handles of the devicewhile the numeral 2 designates the cooperating handle. Each of thesehandles is formed at one end with a head 3 having a central aperturetherethrough for the reception of the pivot bolt 4 by means of which thedevice is held in assembled position and formed on the handle 1 is a jawmember 5, while the aw member 6 is formed on the handle 2 thus forming adevice which when the handles are closed will move the jaw members toclosed position. Threaded in the aw members are suitable thumb screws 7,the heads 8 of which are knurled to form a gripping surface by which thesame may be turned while the inner adjacent ends of said plate andengage the balance wheel being trued, the free end of the pointer beingcurved downwardly as at 10 for engaging the balance wheel. Thedownturned end 10 is pivoted as at 10 to the pointer so that the samecan swing toward the rim of the bal-- ance wheel when gaging wheels ofdifferent diameters. Formed on each of the jaw members are suitableextensions 13 and 14 respectively and the jaw member 13 .is apertured toreceive a suitable pin 15 while a similar aperture 16 is formed near theouter end of the jaw member 13 and is arranged to aline with a punch 17which is fitted into an opening 18 formed in the jaw member 14 whichpunch is removably secured in place by means of a suitable latch member19. This punch is used for removingthe jewels from a watch and it willbe seen that when the device is manipulated the punch will aline withthe opening 16. Removably secured in an aperture 20 formed in theextreme end of the extension 14 is a pin 21 having formed intermediateits ends a head 22, which is arranged to engage the inner surface of theextension 14 to limit the inward movement of the pin. The inner end ofthe pin has formed integrally therewith a barrel punch 23 whichcooperates with the transversely curved surface 24 formed on the innerface of the extreme forward end of the extension 13. The curved surface24 of the jaw is arranged transversely of the extension 18 and isarranged so as to form a suitable rest or anvil for the watch barrel,when the punch 23 is being used to make a catch in the barrel for thespring. The surface 24: is curved so as to fit any size barrel.

Formed in the end of the handle mem her 1 opposite that hai ing the jawmember 5 formed thereon is a suitable bore 25 for the reception of asuitable centering pin which is arranged to act as a center when thedevice is used as a compass. A bore 26 is formed in the coiipeatinghandle memher 2 opposite the end on which the head 6 is formed and isadapted to receive the shank of a glass cutter so as to hold the same inoperative relation with the point hereinbefore referred to. Formed inthe handle member 2 adjacent the end having the opening 26 formedtherein :is a plurality of notches 27 which are gradiuited in size asshown to receive glass of dilferent thicknesses to grip the same whenbeing broken after having been cut. in order to limit the closing of thejaws and handle members a suitable set screw passes through the handlemember 1 and the inner end of said set screw engages the inner side ofthe handle member 2 as will. be clearly seen upon reference to Figs. 1and 2 of the drawings.

Pivotally connected as at 29 to the handle member 1 is a gage plate 30which is slotted as at 31 to receive the shank of a set screw 32 whichis adapted to be threaded into the handle member 2 and this gage plateis" provided with a plurality of graduations 33 for cooperation with aV-shaped mark 3i formed on the handle member 2 so as to in dicate thedistance between the center and the glass cutter when the device is usedto cut glass. In order to provide a wire cutter each of the heads 3 isprovided with a suitable notch 35 through which the wire is passed andit will be seen that upon closing the handles the same will be cut.

Vhile in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the invention as claimed.

\Vhat is claimed is A device of the class described comprising a pair ofpivotally connected handles, heads formed on the forward ends of thehandles, jaw members formed integrally with the heads, adjustablesupports carried by the jaws and arranged in direct alinement with eachother, bearings formed on the adjacent ends of the supports and arranged to rotatably receive the terminals of the balance staff of awatch, a slotted plate mounted. on one of the jaws, a set screw carriedby the jaw and extending through the slot of the said slotted plate andarranged to engage the outer surface of the plate to hold the same inadj i'lsted position, a pointer pivotally secured to the lower end ofthe plate and arranged to swing at right anglesthereto, the outer end ofthe pointer being turned downwardly for engaging the balance wheel, saiddownturned end being pivotally connected to and arranged to swing atright angles to the plate, as and for the purpose specified.
